On June 6, 1933, America's first drive-in movie theater opened in Camden, New Jersey. Once a source of great summer amusement drive-ins began their decline in the 1970s thanks to increasing real estate values, day-light savings time and the popularity of the bucket seat in automobiles.

KEARNEY, NE - JUNE 24: People watch a movie at the Kearney Drive-In June 24, 2007 in Kearney, Nebraska. Since its opening in 1952, the Kearney Drive-In remains popular among families, as children are not charged admission, but may close next year due to the lease expiration. Kearney Drive-In is one of the only two drive-in movie theaters left in the state of Nebraska from over fifty. Drive-in movie theatres were once a symbol of American road culture but most of them are closing in recent years as more Americans prefer go to Megaplexes or watch movies at home.

Movie goers pull into Bengies Drive-In Theatre in 2005 in Baltimore, Maryland, one of the few such nogalistic movie theaters in the US.

A movie screen stands overgrown at the Mountain Drive-In on July 5, 2012 in Liberty, New York. The drive-in closed after it's 1997 season. The area was home to many Borscht Belt hotels that shut down over the years, starting an economic decline in the town of Liberty and surrounding Sullivan County that the community has failed to reverse.
